This is a big digital clock using 2.3" LED displays for the hours and minutes. It can operate in 12-hour or 24-hour mode. The software program including a time adjustment mode can control the clock to a few seconds a year. This project was originally published in the Australian electronics magazine Silicon Chip , march 2001.

More details

The Big PIC Clock is based on a PIC16F84 microcontroller. The software in the microcontroller allows for accurate time keeping. It uses 2.3 Inch (57mm) large seven segment LED for display of hours and minutes and smaller 0,56 inches LED for the seconds.

The circuit incorporates a dimming feature so that at night the reduced ambient light is sensed and the display is dimmed. Before constructing the clock please read through the following theory about clock adjustment and setting and the general circuit description in the manual.
